configure: ffmpeg troubles

Greetings,

I'm trying to build transcode 1.10 on Lenny. (starting with out of box
./configure)
 I always get the following error:

<snip>
ERROR: requirement failed: cannot link against libavformat
libavformat can be found in the following packages:
  libavformat  http://www.ffmpeg.org/
<snip>

I have tried two appropaches:

#1:  I've built ffmpeg from source (#define FFMPEG_VERSION "SVN-r16504").
I made sure paths are set correctly for libavformat, and then set config
flags
as in:

<snip>

  *libavcodec* (FFmpeg) >= 0.4.9-pre1  http://ffmpeg.sourceforge.net/
    *related options:*
      --with-libavcodec-prefix=PFX (/usr)
          prefix where libavcodec is installed
      --with-libavcodec-includes=DIR (/usr/include)
          prefix where libavcodec headers are installed
      --with-libavcodec-libs=PFX (/usr/lib)
          directory where libavcodec libraries are installed
      --enable-libavcodec-static (disabled)
          link binaries and modules statically to libavcodec

<snip>

and the libavformat library is found here (as a static build):

itslab@roadstripe:/usr/local/lib$ ls libav*
libavcodec.a  libavdevice.a  libavformat.a  libavutil.a
itslab@roadstripe:/usr/local/lib$


#2: I utilized the Debian packages (as found with apt-cache search libav)

<snip>
itslab@roadstripe:/usr/local/lib$ ls /usr/lib/libavform*
/usr/lib/libavformat.a   /usr/lib/libavformat.so.52
/usr/lib/libavformat.so  /usr/lib/libavformat.so.52.7.0
itslab@roadstripe:/usr/local/lib$
<snip>


any help would be greatly appreciated.

thanks,
Ted
